I am running the query script via command line.
If customer is not running via command line then they can simply use the List option as shown below
If using Command line use below syntax
User would need to pass it -rtv"MARA.MATNR#Value1#Value2|Value3##Value4|Value5|Value6" where each value is a part of the list you want passed.
Single “#” is used as value separator for a field and Double “##” in below query means there is no value specified for a field.
“ | “ is for in list, between and not between.
Also; follow the below article.
